Epicena Vacuus, also known as Paginis, is a very rare disorder that develops in the womb. For unexplained reasons, the sex chromosomes take the form of "Z" resulting in a sexless individual. Those who suffer from Paginis have neither sex organ and develop no distinguishing traits.
The mysterious combination of a penis and a vagina that is found on certain intersexes and hermaphrodites. An organ that can neither be classified as a really huge clitoris or a really small penis. Fused labia can only be deferentiated from a tiny scrotum by poking around for testies and/or ovaries.
Not to be confused with the vapena, the pegina, or the vagipenialginas
You - what the heck it that?
Hermaphrodite - oh, that's my paginis, do you like it?
You - I'm not sure. How does it work?
